Four years. Forty eight months. Two hundred and eight weeks. Fourteen hundred and sixty days. Some say that it seems like a millennial has passed. It's easy to say that when you see it like that. But it's only four years. It's been four years since Mikan Yukihara left Japan. It's been three since Natsume woke up and couldn't remember her or anything that happened. It's been two since Youichi took over the school. It's been one since they stopped looking for her. What happens when Mikan and Natsume's paths cross once more? She's the girl who he's supposed to protect. Will history repeat itself or will it leave them with a happy ending?
